weeee Woooooooot! I finally got it to work. Thanks for the guide, I never would have gotten anywhere at all without it! And thanks to the rest of you that helped via their responses to other people's issues here. I also wanted to state what I was doing wrong and how I finally got it working in case anyone else had the same issue as myself. Try as I might, I just could not get the mspformat to work and still have my card reader recognize the card. So I ended up having to format in other ways (psp format, manual format, dos promot format as someone quoted earlier here). It turns out that none of these worked when it came to the msinst program. I never got the Y prompt. What I finally ended up doing is using the psp through the usb conection. Using this I was able to use the mspformat program and still read my card afterwards to move forward in the steps. From this point on everything worked perfect as it should. Also I noticed the card was readable in my non laptop pc too. It was just this one reader that didn't read it. So many some card readers don't work with the format the program puts the card in? Also, to get the mspformat to work, I had to first format the card using the PSP XMB. It's all working perfectly now. Very happy with the sliim, and I'm glad I have everything working as I had on my psp1000 now. Thanks again!
